Hello
I recently installed a PS3 upgrade kit in my PRR T1 which was PS1. The installation part went well, but I am having trouble loading the sound file. I followed the directions on MTH website. The 1st try the whistle, bell & chuff seemed OK, but the cab chatter sounded like Alvan & the Chipmonks! I tried another file, but the whistle did not work correctly & there was no chuff. Now, after a few more unsuccessful attempts, I get an error message & the files will not load at all (please see attached photo of message).
Can someone please tell me what I am doing wrong, and how to fix it?
Thank you
